IMS DB/DC issue

We are trying to access the system defined transaction IVTNO for IMS version 14. We can't able to add any data to the table/can't retrieve any data for this Transaction. Shall we need to do anything. Kindly let us know how to use this transaction.

The "AI" status code is described as : "A data management open error occurred."
.
There can be many reasons for the AI status code, please check the JOBLOGs for the IMS Control Region and DLISAS Region for error messages which may appear at the time of the AI status code. It appears there may be a problem opening a database used by this transaction.
